Incidence and Transmission of SARS-CoV-2 in US Child Care Centers After COVID-19 Vaccines.

Importance: SARS-CoV-2 surveillance studies in US child care centers (CCCs) in the post-COVID-19 vaccine era are needed to provide information on incidence and transmission in this setting.

Objective: To characterize SARS-CoV-2 incidence and transmission in children attending CCCs (students) and their child care providers (CCPs) and household contacts.

Design, Setting, And Participants: This prospective surveillance cohort study was conducted from April 22, 2021, through March 31, 2022, and included 11 CCCs in 2 cities.

No Miracles in Two Minutes: A Randomized Controlled Study on the Impact of Preparatory Expansive Posing on Anesthesiology Residents' Performance in Mock Structured Oral Examinations.

Background: The objective of this study was to evaluate the impact of engaging in preparatory expansive posing on the performance of anesthesiology trainees during a mock structured oral examination.

Methods: A total of 38 clinical residents at a single institution participated in this prospective randomized controlled study. Participants were stratified by clinical anesthesia year and randomly assigned to 1 of 2 orientation rooms to prepare for the examination.

The Burden of Nocturnal Symptoms in Patients with Chronic Obstructive Pulmonary Disease: Results of a Real-World Survey in the USA.

Introduction: Patients with chronic obstructive pulmonary disease (COPD) often have poor sleep quality and report a worsening of respiratory symptoms during night-time. However, current clinical guidelines for COPD management do not specifically consider nocturnal symptoms when recommending pharmacological treatment. This study aimed to better understand the burden of nocturnal symptoms in patients with COPD, and to evaluate the importance of nocturnal symptom control compared with daytime and overall symptom control.

Estimating the burden of adult hospitalized RSV infection including special populations.

Background: Numerous studies in the U.S. have made estimates of the RSV burden among adults that vary widely due to differences in methodology, reliance on influenza surveillance, which does not adequately capture all RSV clinical symptoms, and lack of diagnostic methods to identify RSV when viral loads are low.
